DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 722,896, dated March17, 1903'.

Application filed November 1,1902. Serial No. 129,689. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES PULLAR, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inDumping-Wagons, of which'the following is a specification.

This invention relates to the construction of a wagon which has a bodythat is adapted to be tilted for dumping its load by means of levers andchains operated by a crank and gearing. It is desirable to so constructsuch a wagon that when tipped for dumping the lower end of the body willbe close to the ground in order that the load, if brick, soft coal, orother friable material, may not be broken up when discharged, or if theload is ashes or garbage it may be discharged without falling throughthe air and becoming agitated and spread by the wind, or if it is sandor fine stone it may be sprinkled evenly and in small quantitiesalong aroadway.

The. object of this invention is to provide a low dumping-wagon of thisnature with a;

mechanism that is simple and easy to operate and that is cheap anddurable in con struction.

The wagon that is illustrated as embodying the invention has a framesupported upon axles in the usual manner, with a long body that extendsover both axles and is connected with the frame at the rear axleby ahinge and is connected with the frame on each side by a lever that hasone end pivoted to the body and the other end movable along a railattached to the frame. Sprocket-chains that pass around sprocket-wheelson a. shaft that is geared to a crank-shaft are connected with themovable ends of the levers, and the sprocket-shaft is provided witharatchet-and pawl stop and a friction brake mechanism. The body at therear has an adjustable door, whereby the load maybe slowly distributedwhen the body is tilted and the door is open.

Figure 1 of the accompanying drawings shows a side elevation of adumping-wagon having the improvements, with the tilted position of thebody represented'in dotted outline. Fig. 2 shows a plan of a portion ofthe frame, a lever, the operating gearing, and brake mechanism. Fig. 3shows a side elevation of the parts represented in Fig. 2. Fig. 4 showsthe middle isa short shaft 9.

the manner of connecting an end ofa lever with a rail attached to theframe. Fig. 5 shows a vertical section through the rear end of the'body,and Fig. 6 shows an elevation of a part of the rear end of the body.

The frame 1 is mounted upon axles 2, that are supported by wheels 3 inthe usual manner. The body 4:, built to any desired shape, is hinged tothe frame over the rear axle, so that its forward end will extend overand be supported by the front axle. A rail 5 is bolted to the outside ofeach side of the frame. Resting upon the upper edge of each of theserails is a roll 6, that is held in the lower forked end of a lever 7.This roll at the lower end of each lever is kept upon the rail by astrap 8, that extends from the arbor of the roll beneath the rail. Theupper end of each of the levers is pivotedto the side of the wagon-bodya little in front of the middle.

Extending transversely of'the frame near The outer end of this shaft issquare for the application of .a crank 10, and on the shaft just insideof the frame is a pinion. 11. This pinion meshes with a much, largergear 12 on a short shaft 13, provided with. a small pinion 14, thatmeshes with a large gear 15 on the shaft 16. On the shaft-16 each sideof the frame is a sprocket-Wheel 17. Sprocket-chains 18, that areconnected with the lower ends of the le- Attached to one sprocketrwheelis' a ratchetwheel 19. A pawl 20, having a handle 21, is mounted on thestud 22, projecting from the side frame, so as to engage the teeth ofthis ratchet-wheel/ The handle of this pawl is connected with abrake-band 23, that passes around the hub 24 of the ratchet-wheel. Thesprocket-wheels and the ratchet-wheel and its hub are keyed tothe shaft16 in any suitable manner. A yoke-strap 25 is fastened to the side frameto support the end of the shaft. when the crank is turned, the pinionsand gears rotate the sprockets and cause the chains to draw the lowerends of the levers rearwardly along the rails, and thus raise the frontend of the body. The pawl when en-.

gagedwith the ratchet-teeth prevents the parts from turning back andallowing the front end of the body to lower. By means of thisconstruction it is easy to tilt the body,

although it does extend considerably more forward of the hinge than backof the hinge. When it is desired to allow the body to resume its normalposition, the handle of the pawl is depressed, and thislifts the pawlfrom the ratchet-teeth and permits the sprocket- Wheel to turn so thatthe ends of the levers may move forwardly and let the front part of thebody down. A quick downward movement of the handle releases the pawlfrom the ratchet-teeth, but applies friction to the hub, so that thelowering of the front end of the body is under perfect control and maybe accomplished as fast or as slow as desired.

A hook 26 is bolted to the rear of the body on each side. Removably heldby these hooks is a bar 27. Hinged to this bar is a door 28. This dooris provided with bolts 29, that are adapted to be pushed into sockets30, attached to the frame for holding the door closed. Attached to eachend of the door is a notched segment 31, that is adapted to engage a pinprojecting from the side of the body. When these segments are lifted,the door may be swung on its hinges; but when the notches of thesegments are engaged with the pins the door is held against movement. Bythis simple arrangement the door may be fastened shut or held with anopening of any desired extent at the-lower rear end of the body, sothat'when the wagon is tipped, as illustrated by the dotted lines onFig. 1, material may be spread or sprinkled from the body in thequantities desired.

This wagon is very strong. The mechanism is simple and is so arrangedthat it requires but little exertion to dump a heavy load. The body isso hung that the front axle as well as the rear axle supports theweight, and the rear end of the body is quite close to the ground whenit is tipped for dumping, so that material which is liable to be easilybroken may be discharged without damage.

I claim as my invention 1. A dumping-wagon having a frame supported bywheel-axles, a body extending over and supported by both axles andhinged to the rear of the frame, rails secured to the outside of theside bars of the frame, a lever pivoted to the body on each side andhaving a roll resting upon a side rail, straps connect ing the ends ofthe levers with the rails, a transverse shaft provided with a pinion andadapted toreceive a crank, a transverse shaft provided with a large gearthat meshes with the pinion on the crank-shaft and provided with a smallpinion that meshes with a large gear on the sprocket-shaft, asprocket-wheel on the sprocket-shaft outside of each side of the frame,a chain passing around each sprocket-wheel and having an end connectedwith the lower end of a lever, a ratchet-wheel mounted upon thesprocket-shaft, a pawl adapted to engage the ratchet-teeth, a handleadapted to release the pawl from the ratchetteeth and a brake-bandconnected with the pawl-handle and passing around the hub of theratchet-wheel, substantially as specified.
